Cannot use GPU in CPU-only Caffe: check mode

Question

I am using a legacy set up of caffe which is running on CPU.

I switched one line of code from:

caffe.set_mode_cpu()

to:

caffe.set_mode_gpu()

but I get the error:

Cannot use GPU in CPU-only Caffe: check mode.

I checked the Makefile.config and the relevant setting was:

#CPU-only switch (uncomment to build without GPU support)
CPU_only := 1

I assume 1 is True so I changed to

CPU_only := 0

but it did not help.

Any clues?

Comment the line to build with GPU: `#CPU_only := 1` – Miki Nov 02 '16 at 14:56 — Miki, Nov 02 '16 at 14:56
Have you recompiled caffe after you changed CPU_only to 0? – yangjie Nov 02 '16 at 15:52 — yangjie, Nov 02 '16 at 15:52

You need to change:

#CPU-only switch (uncomment to build without GPU support)
CPU_only := 1

to this:

#CPU-only switch (uncomment to build without GPU support)
#CPU_only := 1

and rebuild.
